Comment:

 disregard my cancelled query comment.  I realized those ophans happened
 because I did a select without an insert.

 However the DISTINCT ON case and the select without insert does
 demonstrate that the relations table and summary stats can easily get out
 of synch with reality. Perhaps the only sane thing to do is to provide a
 cleanup relation function that interogates the tables to verify the
 topogeom still exists.
